Explore: Soil Matric Potential

tensiometer in soil science is a measuring instrument used to determine the matric water potential ( Ψ m {\displaystyle \Psi _{m}} ) (soil moisture tension)

concept of water potential has proved useful in understanding and computing water movement within plants, animals, and soil. Water potential is typically

called water potential. Total water potential is a sum of matric potential which results from capillary action, osmotic potential for saline soil, and gravitational
